New feature in VOSS 3.1 is Persistent Continuation Transactions:

An open Continuation Transaction which has committed a number of alternative
futures for its set of objects in continuation sub-transactions may now itself
be persisted, or persisted & deactivated, which removes the live transaction
from the image, allowing log-off and shutdown. Re-activation re-creates the live
transaction.

VOSS 3.145.00.10 (beta) virtual object system for Visual Age Smalltalk is
available for download on http://voss.logicarts.com/downloads under GPLv3 Open
Source and/or Commercial licensing.
